Should there be a comma before "which"?

In a statement on its official Facebook page, the Air Force said an F/A-18D Hornet and a Sukhoi Su-30 MKM were deployed to escort the Boeing 737-82Z (BBJ2) which was carrying Sultan Ibrahim to be sworn in at Istana Negara on Wednesday (Jan 31).

Should there be a comma before "which"?

Thanks.
